In addition to industrial applications of variable-speed motor drives, the home appliance market is another major area where three-phase pulse width modulated (PWM) motor control drives are finding ...

Furnaces with variable-speed blower motors are becoming more popular - no question about it. The benefits include electrical efficiency because a variable-speed motor consumes less energy than a ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

NovaTorque Inc.’s family of Gen2.0 PremiumPlus+ Electronically Commutated Permanent Magnet (ECPM) motors will soon be available in high speed 3hp and 5hp 2400 rpm (maximum speed 3600 rpm) models. Also ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

“Variable speed compressors and drives act similarly to a car’s accelerator pedal, which enables the driver to control and match the speed of the car to their exact needs at any given moment or road ...

Designed for high-pressure applications, Oneida Air’s Smart Boost dust collectors combine variable speed fan motors with the separation performance of a cyclone. Powered by brushless motors, the ...

ABB is changing the energy efficiency game with its innovative LV Titanium Variable Speed Motor (VSM) platform that makes specification and installation of a speed-controlled motor fast and simple, ...

“A bunch of things are coming together.” That's how V Sukumar, a senior applications manager for Fairchild Semiconductor, begins a discussion of trends in motor control for the white-goods market.
